Answer:

Step-by-step explanation:

Given that the  mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

X is N(25, 1)

a) Normal curve is in the attached file

b) the probability that a randomly selected fertilized egg hatches in less than 23 days

=P(X

we convert x into Z score and use std normal distn table to find probability

P(X

i.e. we can say only 2.5% proportion will hatch in less than 23 days.

Masja [62]

Answer:

The answer is

\frac{ {x}^{2}  - n}{m}  =  { (\frac{ {a}^{2} }{b}) }^{a}  \\  {x}^{2}  - n =  m{( \frac{ {a}^{2} }{b} })^{a} \\  {x}^{2}   = m {( \frac{ {a}^{2} }{b} )}^{a}  + n \\ x =  \sqrt{m {( \frac{ {a}^{2} }{b}) }^{4}  - n}

A/4 - 5/6 = 1/2<br> a/4 - 5/6 = 1/2 help
alexgriva [62]

Answer:

a = 16/3 or 5 1/3 or 5.33...

Step-by-step explanation:

to find a you must first make all of the denominators the same

you must find 4 6 and 2s CGF

and that is 12

so multiply a/4 by 3/3 and get 3a/12

then multiply 5/6 by 2/2 and get 10/12

and lastly multiply 1/2 by 6/6 and get 6/12

at this point you can set the equation up like this

3a/12 - 10/12 = 6/12

but then you can multiply everything by 12

3a - 10 = 6

and then solve

add 10 to both sides

3a = 16

then divide 3 on each side

a = 16/3 or 5 1/3 or 5.33...

A country's population in 1995 was 32 million. In 1997 it was 34 million. Estimate the population in 2003 using the exponential
fomenos
Hello! Looking at the numbers, you can see that the population of a country goes up by 1 million people each year. You could also say that it goes up by 2 million every 2 years. At this rate, the population in 2003 was 40 million. This is because 1997-2003 are 6 years apart. Do 1 million * 6 to get 6 million and add that to 34 million from 1997 to get 40 million in 2003.
